The other day I noticed that default_gdb_start reuses the GDB process
if it has been spawned already:
proc default_gdb_start { } {
...
if [info exists gdb_spawn_id] {
return 0
}
I was a bit surprised, and so I hacked in an error to check whether
anything is relying on it:
+ if [info exists gdb_spawn_id] {
+ error "GDB already spawned"
+ }
And lo, that tripped on a funny buglet (see below). The comment in
reread.exp says "Restart GDB entirely", but in reality, due to the
above, that's not what is happening, as a gdb_exit call is missing.
The test is proceeding with the previous GDB process...
I don't really want to go hunt for whether there's an odd setup out
there that assumes this in its board file or something, so for now,
I'm taking the simple route of just making the test do what it says it
does. I think this much makes it an obvious fix.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
